Method of forming phthalate-based ester compound

The present invention relates to a method for preparing a phthalate-based ester compound. More particularly, the present invention includes: a first step of providing a phthalic anhydride and an alcohol to a first reactor, followed by heating; and a second step of performing an esterification reaction by providing the first liquid mixture of the first step to a second reactor. The present invention can reduce the reaction time in the second reactor and improve the production amount of the phthalate-based ester compound.

A liquid phase oxidation of O-xylene with esterification coupling preparation of phthalic acid diester method

The invention relates to a method for preparation of diester phthalate by o-xylene liquid-phase oxidation and esterification coupling. In the presence of a catalyst, air or oxygen is used as an oxygen source for preparation of the diester phthalate by o-xylene liquid-phase oxidation and esterification coupling. The method has the advantages of mild reaction conditions, safe operation, low raw material and energy consumption, high conversion rate and high selectivity and the like.

A manufacturing method for cyclohexane polyacid ester

The present invention provides a manufacturing method for cyclohexane polyacid ester, comprising an esterification step and a hydrogenation step. The esterification step is to esterify benzene polycarboxylic acid or anhydride thereof with alcohol to form a crude product of benzene polycarboxylic acid ester, in which the crude product of benzene polycarboxylic acid ester contains excess alcohol. The hydrogenation step is to hydrogenate the crude product of benzene polycarboxylic acids ester under no purification condition with excess alcohol in a catalyst-containing continuous fixed-bed reactor to form the cyclohexane polyacid ester. The manufacturing method for cyclohexane polybasic ester provided by the present invention can reduce purification processes which are complicate and energy-intensive. Furthermore, the hydrogenation is performed under a lower hydrogen pressure such that the process cost is effectively reduced and the hydrogenation rate of the benzene ring is higher than 99.9%.
